Is converting to a Roth IRA worthwhile? The key factor to consider

Traditional and Roth IRAs can both play an important role in retirement planning. In this guide, Intuit TurboTax explains how to think about which one may fit your situation best.

A Traditional IRA offers a tax break now, while a Roth IRA offers one later in retirement. A conversion means paying the tax upfront so withdrawals can be tax-free later. In either case, the money is taxed only once, at the rate that applies in the year it is taxed.

That leaves one central question: which tax year will likely have the lower rate — now, or when you would otherwise take the money out?

What is a Traditional IRA?

A Traditional IRA lets you deduct your contribution from your taxable income for that year. In other words, the amount you put into the account reduces the income reported on your tax return.

If you have a 401(k) or another workplace retirement plan, your ability to deduct a Traditional IRA contribution may be limited by income. Withdrawals before age 59½ can trigger a penalty, with some exceptions, and required minimum distributions begin at age 73. When you take money out, it is taxed as ordinary income at the rate in effect that year. That can work well for people who expect to retire in a lower bracket, although that is not always the case.

Traditional IRA as a piece of the pie

One way to picture it is to think of your annual income as a pie that gets taxed. A Traditional IRA removes a slice before the government takes its share, leaving less income exposed to tax. The benefit is not extra money; it is simply that less of your income is taxed right away.

What is a Roth IRA?

The Roth IRA works in the opposite way. You do not get a tax deduction when you contribute, but the money can grow tax-free.

You can withdraw your direct contributions from a Roth IRA at any time without taxes or penalties. After the account has been open for five years and you are at least 59½, earnings can also be withdrawn tax-free. Roth IRAs do not require distributions at any age. They also have income limits; for 2026, the phase-out starts at $153,000 for single taxpayers and $242,000 for married couples filing jointly.

Roth IRA as a piece of the pie

With a Roth IRA, the tax bite happens first. The government takes its share before you set the money aside, and then the growth builds inside the account without future tax. By retirement, that money has become its own larger pie, and the government does not take another slice.

Why convert to a Roth IRA?

A conversion moves money from a Traditional IRA, or in some cases directly from a 401(k), into a Roth IRA. You must pay tax on the amount converted, but once the money is inside the Roth account, it is not taxed again.

Conversions from a Traditional IRA to a Roth IRA must be completed within 60 days to qualify as a conversion contribution. Current law also allows a direct conversion from a 401(k) to a Roth account.

How to decide

The key is whether you are likely to face a higher tax bracket later. You cannot know your future rate exactly, but you can make an estimate. Early in a career, income and tax rates are often at their lowest. Near retirement, you can estimate future tax exposure by adding expected Social Security and pension income.

It may deserve a closer look if you are in the 10% to 12% bracket, expect your income to rise, can pay the conversion tax with money outside the IRA, and have time for the account to grow tax-free.

It may be better to wait if the conversion would push you into a much higher bracket this year, if you would have to use IRA money to cover the tax, or if you expect to be taxed at a lower rate in retirement anyway.

The bottom line

Either type of IRA can support retirement goals. The better choice depends on your own financial situation.

Traditional vs. Roth IRA made simple

A Traditional IRA gives you a tax break now. A Roth IRA gives you one later. A conversion shifts the tax bill to the present so withdrawals can be tax-free in the future. Either way, the money is taxed only once.

That brings the decision back to one question: which tax year is likely to have the lower rate — the current one, or the one when you would otherwise withdraw the money?

What is a Traditional IRA?

A Traditional IRA allows you to deduct your contribution from taxable income in the year you make it. The deposit reduces the income shown on your tax return.

If you participate in a 401(k) or similar workplace plan, your ability to deduct a Traditional IRA contribution may be limited by income. Withdrawals before age 59½ can trigger a penalty unless an exception applies, and required minimum distributions start at age 73. When you take money out, it is taxed as ordinary income at the rate in effect at that time. This can be advantageous for those who expect to retire in a lower bracket, though there is no guarantee.

Traditional IRA as a piece of the pie

Think of your yearly income as a pie that is taxed by the government. A Traditional IRA removes a portion before taxes are applied, leaving less income to be taxed. That is the benefit: less of your income is taxed up front, so your overall tax bill can be lower.

What is a Roth IRA?

The Roth IRA is essentially the mirror image of a Traditional IRA. Contributions are not deductible, but the account can grow tax-free.

You may withdraw your direct contributions at any time without taxes or penalties. After the account has been open for five years and you are at least 59½, earnings can also be taken out tax-free. There are no required minimum distributions at any age. Roth IRAs also have income limits; for 2026, the phase-out begins at $153,000 for single filers and $242,000 for married couples filing jointly.

Roth IRA as a piece of the pie

With a Roth IRA, the tax is collected before you contribute. After that, the money you save grows on its own and is not taxed again when you withdraw it in retirement. The growth belongs entirely to you.

Why convert to a Roth IRA?

Moving money from a Traditional IRA, or directly from a 401(k), into a Roth IRA is known as a conversion. The converted amount is taxable now, but it will not be taxed again once it is in the Roth account.

A Traditional IRA-to-Roth IRA conversion must be completed within 60 days to count as a conversion contribution. Current law also allows a direct move from a 401(k) to a Roth account.

How to decide

Consider whether your tax rate is likely to be higher later. While you cannot know for sure, you can estimate. Early in your career, income and taxes are often lower. Closer to retirement, you can get a more concrete estimate by adding up expected Social Security and pension income.

It may be worth a closer look if you are in the 10% to 12% bracket, expect higher earnings ahead, can pay the conversion tax from savings instead of IRA funds, and have years for tax-free growth.

It may be better to wait if the conversion would move you into a much higher bracket this year, if you would need IRA money to cover the tax, or if you expect a lower tax rate in retirement.

The bottom line

Both IRAs can be effective retirement tools. The best choice depends on your personal financial circumstances.
